GETTING
STARTED
The installer should review these points with the homeowner and answer any questions they have before
leaving the job site.
• Achieving Humidity Setpoint. It may take up to a week of continuous operation to achieve the humidity
setpoint, especially if the home is dry when the humidifier is installed. This also depends on such factors
as weather, size of home, furnishings in the home, and insulation.
• Ideal Humidity. Home building industry experts cite 35% relative humidity as ideal for comfort and
safeguarding the home during the typical dry season. Homeowners can adjust to their own comfort or
until there is condensation on the windows. Lower the setpoint if condensation appears.
• Unit Not Humidifying. If the humidifier is not running but the humidity is below the setpoint, the
humidity control may have a frost protection setting to prevent window condensation from appearing.
• Home Ventilation. Excessive ventilation sends moist air outside and replaces it with dry air. This can
make it hard to maintain the humidity setpoint. If installing a ventilator, use a solution that retains
moisture. An Energy Recovery Ventilator (ERV) is recommended.
• Cleaning Requirements. The humidifier pad should be changed at least once a year. The water trays of
the humidifier should be cleaned at that time. See Operation and Service section for details.
• Energy Consumption. It is important to explain that with any humidification solution there is a cost
associated with converting water to humidity. The humidifier utilizes the air heat and air flow in your
ducting to make this conversion, which has gas and/or electric costs that depend on your HVAC system
type and setup.
What to Expect From Your Humidifier
Humidifier 33-00617EFS—01 3

GETTING
STARTED
Personal Safety
• Wear safety glasses while installing the humidifier.
• Do not cut into any air conditioning or electrical line.
• Follow professional safety standards and all local regulations for plumbing, electrical, and mechanical
considerations.
Mounting Location
• Mount the humidifier in a level position to avoid water damage and ensure maximum output.
• Location must have access to a water line, drain, and power.
• Do not install the humidifier where the ambient temperature is lower than 34°F (1.1°C) or higher than
90°F (40°C).
• Mounting area must be strong enough to support humidifier weight (up to 10 lbs).
• Do not mount directly to ductboard.
• If used near a pool or spa, make sure the humidifier can not fall into the water or be splashed.
• Ensure that the top and bottom covers of the humidifier can be removed and that the pad is accessible
from the chosen location.
Water Supply and Drainage
• Consult local plumbing codes for drain size, material, and maximum temperature allowed.
If Replacing an Old Bypass Humidifier
The humidifier is not identical in size and shape to other bypass humidifiers. Before performing a retrofit
installation, you might need to:
• Dry-fit the humidifier to the existing ducting, plumbing, and wiring before fastening it to the duct to ensure
that the existing connections will reach the humidifier.
• If the duct opening of the old humidifier is not the right size for the humidifier, choose a new location or
cover the old opening with a piece of sheet metal and cut a new opening specifically for the humidifier
using the template provided.
Important Installation Requirements
Failure to comply with these requirements will result in voided warranty, improper installation,
and service callbacks.

MOUNTING
Choosing a Mounting Method
Before beginning Mounting:
I have confirmed local codes for proper plumbing practices.
I have chosen an installation location that meets the requirements on page 4.
Bypass humidifiers use the pressure difference between the supply
and return to move duct air through the humidifier. Access to both
the supply and return are required. The bypass humidifier can be
positioned on either the supply or return duct.
MCR29871
STEP ONE: Select the Mounting Location
Choose a location that has access to a water supply
pipe. Cold or hot water can be used.
Select a vertical or horizontal surface on the HVAC
duct work, with adequate space clearances, where
the humidifier can be mounted.
Ensure the location is near a drain. Consult local
plumbing codes for proper drainage. If no main
floor drain is available, see “Appendix B: Advanced
Draining.”
Location must also have access to 120 VAC power to
the included transformer.

STEP TWO: Install Mounting Template to the Duct
Position the template on the duct.
• Make sure the template is level and in the desired
position on the duct. Peel adhesive backing
and press template firmly into place in desired
mounting location.
Ensure proper clearances from the air-conditioning
coil inside the duct.
NOTE: The HE400 humidifier extends into the duct
1/2 inches.
• For best performance, maintain at least 24
inches downstream of open air space inside the
duct.
Cut the sheet metal, following the template outline.

MOUNTING
Ensure that the pad is accessible. The handle of
the pad holder and side panel of the humidifier
can be switched so the pad holder can be removed
(opposite side of the bypass duct opening).
To remove the handle for the pad holder, slide it
toward the back of the humidifier, then pull it away
from the humidifier.
To remove the opposite side panel, place a
screwdriver into the two slots on the back of the
humidifier, and pop the panel off.
Snap the pad holder handle and side panel back into
place in the desired configuration.
STEP FOUR: Mounting
Secure the support hooks on Bypass models to the
bottom lip of the hole.
Push the top of the humidifier back against the duct.
Verify the humidifier is level and fasten the
humidifier to the duct using two self-drilling sheet
metal screws provided.

STEP FIVE: Bypass Duct Installation
On the duct opposite the humidifier Bypass install,
cut a 6-in. diameter duct hole.
• If the humidifier is on the supply duct, the 6-in.
diameter hole should be on the return.
• If the humidifier is on the return duct, the 6-in.
diameter hole should be on the supply.
Secure a 6-in. round duct starter collar into the 6-in.
duct hole.
Use rigid or aluminized flexible 6-in. duct to connect
the starter collar to the humidifier bypass port.
Secure the duct to the humidifier port with self-
drilling sheet metal screws using the pre-drilled
holes on the bypass port. For added seal, wrap sheet
metal tape around the duct to port connection point.

to the main water supply tap.
Insert the water line into the gray quick connect
fitting. Insert it fully, and apply modest pull pressure
to ensure a tight fit.
Note: The quick connect fitting can be removed
if you prefer to use a standard 1/4-in. brass
compression nut plumbing connection. Do not
remove the filter if you select this option.
STEP TWO: Tap into a Water Line
• Consult local codes for proper plumbing.
• Use the saddle valve provided or a T-fitting and
manual shutoff valve to tap into the water line.
• Refer to the literature included with the valve you

STEP THREE: Connect to the Water Drain
• Consult and follow local plumbing codes for drain
pipe size and flow requirement.
• The ideal installation is directly to the main floor
drain using the rubber hose provided.
• If direct floor drain access is not available, see
“Appendix C: Advanced Draining.”
Connect the 1/2-in. drain hose provided to the drain
fitting on the bottom of the humidifier.
Use the hose clamp provided to secure the drain
hose to the fitting.
Route the drain hose to the floor drain. The hose
must have a continuous downward slope.

Wiring the Outdoor Sensor
CAUTION: Electrical Interference (Noise) Hazard. Can cause erratic system operation.
Keep wiring at least one foot away from large inductive loads such as motors, line starters,
lighting ballasts and large power distribution panels.
Use shielded cable to reduce interference when rerouting is not possible.
Be sure wires have a cable separate from the thermostat cable.
Do not route temperature sensor wiring with building power wiring, next to control
contactors or near light dimming circuits, electric motors or welding equipment.
Avoid poor wiring connections.
Avoid intermittent or missing building earth ground.
CAUTION: Electrical Shock Hazard. Can cause electrical shock or equipment damage.
Disconnect power supply before connecting wiring.
Wiring must comply with applicable codes, ordinances and regulations:
1. Wire the C7089 Outdoor Sensor to the S terminals on the humidity control.
If leadwire provided with C7089 is not long enough (60 in.), run a cable to a
hole at C7089 location.
• Using color-coded, 18-gauge, shielded thermostat wire is
recommended. For example of general wiring of C7089, see image
at right.
• Pigtail wiring can be used.
2. Mount C7089 in its mounting clip.

Allow C7089 Outdoor Sensor to absorb outdoor air for a minimum of twenty minutes before taking a reading.
With an accurate thermometer (±1°F [0.5°C]), measure the temperature at the sensor location, allowing time
for the thermometer to stabilize before reading.
Then verify the sensor accuracy by going into installer Test #20. This will show you the outdoor temperature.
Calibration
The C7089 Outdoor Sensor is calibrated at the factory. However, you can offset the outdoor sensor reading
using Function 35 in Installer Setup.
You’ve just installed your Humidity Controller!
This Humidity Control has been preprogrammed to the ideal settings for most homes.
If you installed this control with an outdoor sensor, the control will operate in AUTOMATIC MODE, which
automatically adjusts humidity to help prevent window condensation.
If you installed this control without an outdoor sensor, the control will operate in MANUAL MODE, giving the
homeowner simple, direct control of their humidifier (RH% Setting Only).
